A locking mechanism locks a door or panel over an opening to deter breach of the locking mechanism and prohibit unauthorized access. The locking mechanism includes an escutcheon plate which is non-removably secured to the door. This escutcheon plate has a front side and a back side, the front side facing outwardly away from the door and the back side being inserted through a mounting aperture in the door. A latch is operatively attached to the escutcheon plate. The latch is operated by a handle which is movably attached to the escutcheon plate on the outside of the door and which handle is formed with a blocking portion which extends to cover a specific area of the escutcheon plate. A catch member is mounted on the inside of the escutcheon plate and has an operating member which projects through the escutcheon plate to the outside of the escutcheon plate for engaging and disengaging the catch with the latch. Coverage of the escutcheon plate by the blocking portion includes covering access to this operating member.
